将服务添加到您的 OpenStack-Ansible 部署

要将新服务添加到您的 OpenStack-Ansible (OSA) 部署

• 在您的 conf.d 或 openstack_user_config.yml 中定义 orchestration_hosts。例如

  orchestration_hosts:
    infra1:
      ip: 172.20.236.111
    infra2:
      ip: 172.20.236.112
    infra3:
      ip: 172.20.236.113
  

• 创建相应的 LXC 容器（跳过金属部署中的此步骤）

  openstack-ansible openstack.osa.containers_lxc_create --limit heat_all,orchestration_hosts
  

• 运行服务部署 playbook

  openstack-ansible openstack.osa.heat
  

有关更多信息，请参阅 OpenStack-Ansible 项目文档。

始终验证集成是否成功以及服务是否在生产环境中使用前表现正确。

示例 playbook

---
- name: Install heat server
  hosts: heat_all
  user: root
  roles:
    - role: "os_heat"
      tags:
        - "os-heat"
  vars:
    external_lb_vip_address: 172.16.24.1
    internal_lb_vip_address: 192.168.0.1
    heat_galera_address: "{{ internal_lb_vip_address }}"
    keystone_admin_user_name: admin
    keystone_admin_tenant_name: admin
    galera_root_user: root
  vars_prompt:
    - name: "galera_root_password"
      prompt: "What is galera_root_password?"

标签

此角色支持两个标签：heat-install 和 heat-config。可以使用 heat-install 标签进行安装和升级。可以使用 heat-config 标签来维护服务的配置。

Heat 客户端端点

当您的虚拟机需要与您的 API 通信时，您可能需要更改 Heat 配置。默认情况下，Heat 配置为使用内部 API 端点。如果实例或创建的容器需要访问 API（例如 Magnum、Heat Signaling），则需要使用以下示例中的公共端点

heat_heat_conf_overrides:
  clients_keystone:
    endpoint_type: publicURL
    auth_uri: "{{ keystone_service_publicurl }}"
